Tsutomu Kajihara knives are made in Tosa Japan. Mr. Kajihara is a third generation blacksmith and he is 64 years old. These knives are have really nice grinds and nice damascus patterns on the blades and they're made with high quality Aogami #2 (Blue Paper #2) steel with good heat treatment and high hardness at HRC62. The handles on these knives are D-shaped, made of rosewood with ebony ferrules.
I purchased the knife for use in a restaurant i work for which I would be doing a lot of prep work of all types. The knife is absolutely beautiful,has great fit and finish and the handle is lovely so far I’ve had it I think about two weeks and I only recently sharpened it not because it was dulling because it was still razor sharp after lots of heavy use I just wanted to see how far I could push the edge and how well it sharpened and wow the grind on this knife is awesome it has a complex grind that on the right side of the user the blade is concave and the left side is convex so when cutting veggies they fall off the blade with ease,very unique and nice touch,so here’s the only problem I’ve found. The blade patinas and rusts super crazy easy like wow you leave it ten minutes without wiping it and you have permanent marks that will have to be carefully polished out so if you’re planning on being in a stressful environment where keeping this blade dry might slip your mind it could be a problem. I have really enjoyed using this knife thus far plus I get many compliments around the kitchen about how beautiful the blade is,I’d say the knife would be absolutely exceptional for home use and also great for prep if you’re a very meticulous organized user. Beautiful knife this blacksmith is a true artist who has created a very unique blade with the complex grind setting it a part I recomend it 100 percent
